In a family with 2 children, the probability that both children are girls is approximately .25. In a random sample of 1,000 families with 2 children, what is the approxi-mate probability that 220 or fewer will have 2 girls

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

i think the answer is b. i hope i !

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2

choice b
